Dab tsi yog txoj kev loj hlob ntawm high-power LEDs?
1. Tseem muaj ntau chav rau high-power LED teeb efficiency txhim kho. LED teeb pom kev zoo tau dhau los ntawm peb tiam dhau los ntawm cov teeb pom kev zoo, tab sis nws tseem nyob deb ntawm qhov theoretical siab tus nqi, uas txhais tau hais tias nws tseem muaj peev xwm loj hlob. Sab hauv quantum efficiency ntawm LEDs tuaj yeem siab heev, feem ntau siab dua 90%, tab sis sab nraud quantum efficiency feem ntau qis heev. Yog hais tias sab nraud quantum efficiency tuaj yeem txhim kho tau zoo, qhov ua tau zoo ntawm LED cov khoom tuaj yeem txhim kho tau zoo. Qhov no yog ib qho ntawm cov kev tshawb fawb tseem ceeb ntawm kev coj.
Siab zog LED
Tsis tas li ntawd, thaum tham txog lub teeb pom kev zoo ntawm LED lub teeb qhov chaw, ntau lub tswv yim yuav tsum paub qhov txawv. Lub teeb pom kev zoo ua tiav los ntawm LED teeb qhov chaw hauv chav kuaj tsis sawv cev rau lub teeb pom kev zoo ntawm cov khoom uas twb muaj lawm. Nws kuj yuav tsum tau daws cov teeb meem xws li cov txheej txheem ntau lawm ua ntej nws tuaj yeem hloov mus rau hauv cov khoom siv batch. Yog li nws sawv cev rau lub teeb nyhuv ntawm cov khoom yav tom ntej. Qhov thib ob, lub teeb pom kev zoo ntawm cov khoom lag luam qis qis qis tsis sawv cev rau lub teeb pom kev zoo ntawm cov khoom lag luam xim siab.
Thaum qee cov tuam txhab txhawb nqa lawv cov khoom, lawv hais tias ntau npaum li cas lumen watts lub teeb ua haujlwm ntawm cov khoom ncav cuag, uas yog tus nqi ntawm LED lub teeb qhov chaw nrog cov xim qis qis, thiab LED teeb pom kev zoo nrog cov xim rendering siab tsis tuaj yeem. ncav cuag tus nqi tshaj tawm. Tsis tas li ntawd, lub teeb ci LED, cov xim kub kub lub teeb muaj txiaj ntsig zoo dua li cov xim tsis muaj xim, thiab 5600K LED muaj txiaj ntsig ntau dua li 3200K LED. Kev nkag siab txog cov yam ntxwv ntawm LED yog yooj yim rau kev yuav khoom ntawm cov khoom tsim nyog.
2. Kev txhim kho cov xim rendering Performance index yog ib qho tseem ceeb ntawm LED teeb qhov chaw. Feem ntau, qhov siab dua cov xim rendering Performance index, qhov qis dua qhov luminous efficiency; qhov siab dua qhov luminous efficiency, qhov qis ntawm cov xim rendering Performance index. Qee daim ntawv thov, xws li zaj duab xis thiab TV, theem teeb pom kev zoo, muaj qhov xav tau siab ntawm cov xim rendering Performance index ntawm lub teeb ci.
